T aZZ whom it may concern: trough. The oil to be burned is supplied toBe it known that I, LOUIS GODDU, of Winthe shallow trough through a pipecommunichester, county of Middlesex, State of Massa-- eating with theoutlet-port of a valve-casing chusetts, have invented an Improvement incontaining, preferably, two independent Petroleum-Burners, of which thefollowing valves, one of which is controlled by the 5 5 description, inconnection with the accompapressure in the boiler to cutoff the supplyof n ying drawings, is a specification, like letters oil to the burner,the other of which is oper on the drawings representing like parts.atively connected, as will bedescribed, to a This invention relates toapparatus for regulator, which may be a float located in a T0 burningoils, especially unrefined oils, such chamber or vessel communicatingwith the 60 as crude petroleum, and is an improvement interior of thedeflector referred to, so that upon the apparatus shown and described inexcess of oil in the deflector may flow into another application, SerialNo. 250,705, filed the chamber or vessel, and, by raising the by meSeptember 26, 1887. float automatically, cut off the supply to the Priorto my invention I am aware that atburner, or the said regulator may be acup 65 tempts have been made to employ crude peor receptacle connectedto the valve and troleum as a fuel for heating purposes; but adapted toreceive oil from a pipe connected prior to my invention this has notbeen sucto the deflector.

The burner is herein shown as composed of an annular shallow trough at,having secured to or forming part of it an upwardly and preferablyoutwardly expanded or extended side i wall a. The side wall ct isprovided on its outer side, as shown in Figs. 1, S, and 9,with legs orstuds a which project down at intervals, so as to leave an opening abetween every two adjacentlegs for the passage of air. Each dependingleg a as herein shown, is provided with a slot, into which is fitted theupper end of a concaved plate or wall a", constituting adeflector, thesaid legs being secured to the said plate or wall in any desired orsuitable manner.

Thedeflecting-wall a is shown in Fig. 1 as circular in form to conformto the shape of the shallow trough, and the said deflectingwallformswith the outer upturned side of the said trough a passage a throughwhich the flame from the burning oil is directed down under and incontact with the bottom of the shallow trough.

The deflecting-wall a in the present instance is cored annularly nearits upper end above the shallow trough to form a circumferential passagea, having its inlet separated from its outlet by a suitable partition orwall indicated by dotted lines a Fig. 6, the passage a", having itsinlet mouth or port connected to a steam-inlet pipe a, provided with acock or valve a the outlet end or mouth of the passage a communicatingwith the radial passage a formed in the deflecting-wall. The passage toextends down to thebottom of the deflecting-wall a and communicates withthe interior of the burner through a port, which is controlled, asherein shown, by a plug-valve a The steam-inlet pipe (1. in practice isconnected to the steamdome-of the boiler.

The passage cflat its upper end, preferably at the junction of the saidpassage with the circumferential passage 0., may be provided with anoutlet-port a located above the shallow trough a and adapted to admitsteam into the space between the side walla and deflectingwall a, abovethe said trough, the said outletport being controlled, as herein shown,by a plug-valve 17, extended through a hollow arm b of thedeflecting-wall a, the said arm bei ing extended through the side of theboiler,

as herein shown, and provided with a suitable stuffing-box b of anyusual construction.

The oil to be burned, which in practice is preferably crudepetroleum-oil, is supplied to with a suitable valve or cock I). Thethreaded nipple b is preferably connected by a glass or othertransparent tube or pipe 19 to another nipple 19 which communicates withthe outlet-passage I) (see Fig. 11 and dotted lines,

Fig. 3) of a valve-casing 0, herein shown as a tube secured to orforming part of the shell b, it. being shown as secured to the topthereof.

The valve -casing contains, as herein shown, two independent valves 0 cpreferably made as hollow tubes and provided with valve-stems c 0extended through stuffingboxes 0 c, secured to the opposite ends of thevalve-casing c. The hollow valve 0 is provided, preferably, with alongitudinal slot 0 constituting a port, which registers with the port 0in the shell or case b, the port 0 constituting the inlet-port of thevalve. The'hollow valve 0 is provided with a preferably transverse orradial slot 0 to register with the passage 11 the said slot constitutingthe outletport for the valve. The valve is preferably made in twoindependent sections 0 0 so that they may be rotated independently ofeach other, for a purpose as will be described. The valve-stem c has itsendpreferably made square, or of other than round shape, to be engagedby a lever d, to which is connected one end of a link at, having itsother end connected to a weighted lever (P, which is raised and loweredby the steam-pressure within the steam-dome of the boiler acting on adiaphragm d of a regulator of any usual constructiomand such as known inthe market as the Clark regulator.

It will be seen that the supply of oil from the case or shell Z) passesthrough the ports c 0' into the valve 0', and from thence into the valve0 and the said supply will be automatically cut off by rotating thevalve 0 from the position shown in Fig. 2 to that shown in Fig. 11, soas to bring the port 0 out of line with the port 0 which rotation iseffectedby the raising of the lever 61 by the steam-pressure in theboiler.

The valve-stem c of the valve 0 has its end preferably made square, orof other than rounded shape, to be engaged, as herein shown, bya lever dprovided with asegment of a gear c with which co-operates a segment of'agear d on a lever 61 which may be connected by a'link d to a float allocated in a vessel or receptacle (1 the latter having its bottomconnected by pipe (Z to the lower end of the deflecting wall a near thebottom thereof, the lower end of the said deflectingwall being upturnedto form a shallow basin to receive any excess or surplus oil whichmayoverflow from the shallow trough a, the said excess flowing off throughthe pipe (Z into the vessel d, in which it accumulates and raises thefloat, and through the levers d (l rotates the valve 0 from the positionshown in Figs. 2 and 11 to one substantiallyat right angles thereto, soas to bring the port 0 out of line with the passage I), and thus closethe outlet-port of the valve 0 and out oh": the supply of oil to theburner. It will thus be seen that the supply of oil to the burner isantomatically regulated, not only by the steampressure which operatesthe inlet-valve, but also by the excess of oil which operates theoutlet-valve.

The plug-valve a, controlling the admission of steam into the center ofthe burner, is connected to one end of a lever 6, extended beyond oroutside of the boiler, which may be operated by the foot or otherwise.

The boiler will be provided with usual dampers, (not shown,) by whichair may be admitted to the fire-box A In the operation of my improvedburner the oil admitted to the shallowtrough a is ignited, and the airin the fire-box A passes through the spaces a and down through thepassage a carrying with it the flame arising from the burning oil, thesaid flame being thus brought beneath and in contact with the bottom ofthe shallow trough CL, thereby intensely heating the same and enablingthe crudest petroleum to be burned without deposition of residue, thesaid flame passing up into the fire-box, as indicated by arrows.

I have herein shown in Fig. 1 the shallow trough a and its sidewall a ascircular in form, as is also the deflecting-wall a; but I do not desireto limit my invention to this particular shape of apparatus or burner,as it is evident that the same may be changed, according to the kind andshape of boiler with which it is to be usedas, for instance, whenemployed in connection with the locomotiveboiler the said shallow troughmay be made substantially straight and of considerable length, and thedeflecting-wall a in this instance may be made of considerable length toco-operate with the said burner, substantially as shown in Figs. 4 and5, wherein a burner comprising a shallow trough, its side wall, and thedeflecting-wall co-operating therewith are shown.

I have thus far described my improved burner as employed with boilers inwhich a substantially high steam-pressure is attained; but I do notdesire to limit my invention to the use of my improved burner withboilers as described, as it may be used in furnaces and like apparatus,and especially to heat boilers carrying only a low steam-pressuresuch,for instance, as used in apartment hotels for heating purposes.

When used with furnaces, the burner will preferably be madesubstantially as shown in Figs. 8 and 9, the deflecting-wall a at thecenter being recessed or made cup-shaped, as at 25, to receive a smallquantity of water, which may be supplied either by a pipe or nozzle 26,extended up through the bottom of the deflecting wall, as shown in Fig.9, the said pipe or nozzle being connected to a supply-pipe 27, providedwith a cook or valve 28, or the said water may be supplied by a pipe 30,extended through the side of the deflecting-wall and connected to thesupply-pipe 27, as shown in- Fig. 8. The supply-pipe 27 may and preferably will be connected to a supply-tank (not shown) located at asufficient height-as, for instance, at the top of the building-and thesupply of water may be regulated to a nicety by the cook or valve 28, sothat but a single drop of water at a time maybe brought in contact withthe bottom of the deflecting-wall, which bottom being intensely heatedimmediately converts the water into steam, and thus assists and rendersperfect the combustion.

I have herein shown the side wall a as an integral part of the shallowtrough; but it is evident that the said wall may be an independent partfastened in any suitable manner to the shallow trough.

The parts of the burner will preferably be made of iron; but insteadthereof they may be made of fire-clay or other refractory material.

I have herein shown the side wall a provided with lugs which rest uponthe deflecting-wall and leave air-spaces; but I do not desire to limitmyself to this specific manner of supporting the trough and its attachedside wall, as the said parts may be supported by bars 33, secured to thetrough and to the deflecting-wall, as shown in Fig. 10, or in any otherconvenient manner.

Referring to Fig. 7, the overflow-pipe d discharges into a cup or Vessel(Z connected to the valve-stem to close the inlet-valve.

I claim 1. The combination, with a firebox, of a shallow troughsuspended therein to receive and hold the oil to be consumed and adeflector located outside of and extended below and underneath theshallow trough to form a passage for the products of combustioncontiguous to the shallow trough, the air admitted into the fire-boxdrawing the flame from the surface of the oil in the trough down underand in contact with the bottom of the trough, whereby the flame createdin the trough is utilized to heat the trough at its under side to insurea complete combustion, substantially as described.

2. The combination, with a shallow trough to contain the oil in smallquantity to be burned and a side wall extended upwardly from the inneredge of the shallow trough, of a deflecting-wall located outside of andextended downward from the outer edge of the trough to form therewith apassage for the products of combustion contiguous to the outer side ofthe upwardly-extended side wall and through which the products ofcombustion pass down under and in contact with the bottom and inner sideor edge of the said trough, substantially as described.
